Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] Such as figure 1 As shown, in an application scenario of an embodiment of the present invention, several TPs (equivalent to small base stations or micro base station), and these TPs are configured with the same cell ID as the CU, or the TPs and the CU are configured with the same virtual cell ID. The configuration with the same virtual cell ID means that these TPs and CUs are configured with some same wireless resources associated with the virtual cell ID, ...

Abstract

The invention relates to a transmission method and a device of control messages. The method includes the steps as follows: UE (user equipment) in one cell is grouped, and a second control message of each grouped UE group is obtained; the second control message of each UE group is subjected to combined channel coding; a first control message is obtained and transmitted to the UE in the cell, wherein the first control message comprises an indicating message of the second control message of each UE group after the combined channel coding of the second control message, and the second control message is obtained according to the indicating message; and the second control message of each UE group after the combined channel coding of the second control message is transmitted to the UE in the cell. The method groups the UE in the cell, and the UE-level control message in each group is subjected to combined coding and transmission, so that the transmission efficiency of the control message can be obviously improved, the system capacity of a network is enlarged, and the problem that the capacity of a control channel is limited is solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for transmitting control information. Background technique [0002] The downlink of the current wireless cellular communication usually refers to the base station sending a signal to the terminal UE. In the LTE (Long Time Evolution) system of 3GPP (3rd Generation Partnership Project), downlink physical channels can be divided into data channel, control channel, broadcast channel, synchronization channel, paging channel and multicast channel according to their functions. The physical downlink data channel (PDSCH, Physical Downlink Shared Channel) in LTE includes a physical downlink control channel (PDCCH, Physical Downlink Control Channel), a physical control format indicator channel (PCFICH, Physical Control Format Indicator Channel) and a physical HARQ indicator channel ( PHICH, Physical Hybrid ARQ Indicator Channel). In addition, the broadcast...
